How to deal with it

Several days ago I sent a message to him who was a boy I like for many years.I had no enough courage to say that directly.But I don't want the secret in my heart for ever.And I sent a message to him.The words of that message is not so obvious and his answer to this message is also  not so obvious.

  This is the first time to say something to the male,and I feel so shy.How to deal with this?Should I continue to contract with him to get his obvious answer or should I  be disappear from his life?Now I know that he dosen't like me or he will answer to me directly.

  Someone told me that you should do your best to let him notice you.If you don't try your best to do that you will feel regret after several years.But he is my classmate,if there is no result between us there will be bad affection.

  How to deal with this.
